Problem
The first longpress of a button on the Sony Android TV remote control after not having used it for >30s always fails. The action of the shortpress is executed instead
Detailed Description
The Sony remote combines 2 functions:
- infrared for the buttons (keyboard from a Kodi point of view)
- Bluetooth for voice input (joystick from a Kodi point of view)
The Bluetooth part is detected as Joystick inside Kodi, which is suspended after a 30s idle time (see here) and is woken up again when pressing any button, causing the Joystick to be re-detected by Kodi. If the button press which wakes the Bluetooth part is a longpress, the Joystick re-detection seems to reset the key early, effectively resulting in a shortpress. So the Joystick detection seems to have some influence on the keyboard input.
I created a log of the incident:
- play video
- longpress OK: pause
- longpress OK: play
- wait >30 seconds until remote device gets removed
- longpress OK: player controls (shortpress) instead of pause (longpress)

Workaround
Disabling Bluetooth on the Sony Android TV works around the issue, preventing the (re-)detection of the Joystick on a button press inside Kodi. But it obviously kills voice input, therefore rendering the workaround useless.
